Permanent estate thinking in a constrained capital environment
The question facing most schools and multi-academy trusts is no longer whether additional space is needed. It is how to create it in a way that serves the estate well — not just this year, but over the next twenty years.
Modular construction became the default answer to that question for good reasons. Schools face growing pupil numbers, stretched budgets and narrow delivery windows. Speed matters. Cost certainty matters. Modular offered both, and for a period it felt like the obvious route.
The reassessment now happening across many estates teams is not a rejection of those priorities. It is a recognition that the decision-making framework has become more sophisticated — and that the criteria modular was chosen against don’t fully capture what schools are actually trying to achieve.
What estates leaders are now weighing
A decade ago, many expansion decisions were driven primarily by urgency. Get the space. Hit the deadline. Stay within the budget. Those pressures haven’t gone away, but the conversation around them has changed.
Estates directors and MAT leadership teams are increasingly asking questions that go beyond the immediate project: How does this structure integrate with the existing estate? What does it look like in fifteen years? How easy is it to adapt if our needs change? What are the lifecycle costs? What does it say to parents, students and staff about how seriously we take this environment?
These are not abstract questions. They connect directly to student experience, safeguarding, operational efficiency and long-term financial stewardship. Covered social areas affect circulation and behaviour. Dining capacity influences timetabling and flow. SEND environments shape inclusion. Buildings determine how schools adapt to changing curriculum needs over time.
When those connections are made explicit, the calculus around modular starts to shift.
The fragmentation problem
One of the recurring issues facing school estates is the gradual deterioration that occurs when expansion projects are treated as standalone interventions rather than part of a coherent long-term strategy.
Over time, circulation routes become inefficient. Temporary structures remain in place far longer than intended. Visual consistency deteriorates. Social spaces become congested in ways that weren’t anticipated when each individual decision was made. The estate technically meets capacity requirements but struggles operationally — and the accumulated effect of individually reasonable decisions starts to look like a planning problem.
This is particularly acute for MAT estates leaders managing multiple sites over extended investment cycles. Decisions made under short-term pressure shape operational performance for decades. A modular building installed in year one of a ten-year estate programme can constrain every subsequent decision about how the site develops.
Where modular still makes sense — and where it doesn’t
Modular construction has a clear and legitimate role. For temporary accommodation requirements, urgent decant situations or highly standardised teaching environments where speed genuinely overrides everything else, it remains appropriate. The issue is not modular as a category. The issue is modular as a default — applied to projects where the brief actually calls for something more permanent, more integrated and more considered.
The projects where the modular assumption most often breaks down are the ones that involve connecting to existing buildings, responding to complex sites, or creating spaces — dining halls, social areas, SEND provision — where the quality of the environment has a direct effect on how well the space actually works. These are design problems, not product selection problems. And they require a design response.
A different balance
What many estates teams are now looking for is a route that combines the delivery certainty traditionally associated with modular — fixed price, fast programme, single point of accountability — with the permanence, durability and architectural integration that a traditional build delivers. Not a compromise between the two, but a genuinely different approach that doesn’t sacrifice one for the other.
Permanent steel frame design and build — developed specifically for education environments, with design and cost running in parallel from the outset — is increasingly how that balance is being struck. It produces buildings that integrate properly with existing estates, perform well over the long term, and don’t require the school to return to the same problem in ten years.
The most effective estate decisions aren’t always the ones with the lowest upfront cost. They are the ones that deliver the greatest long-term operational value — and leave the estate in a better position to respond to whatever comes next.
